Daniel Belyea
Extremely personable
I used Bay Business Group to prepare my personal and LLC taxes for 2010. They were extremely personable and informative throughout the entire process. I’ll be using them again in a few weeks.

Trevor Lyman
Number savvy
We love Bay Business- they handle so much for us and I trust them to take care of our small business accounting needs. They always go the extra mile and are also friendly and kind when talking with people who are not number savvy.

Lara Howe
"go to" folks!!
Bay Business has done all of our accounting for almost 20 years. They are a wonderful company to deal with. They are responsive, extremely helpful and friendly and I would add, never make us feel like we are unreasonable when we make special requests. We deal mostly with Mary and Valerie and they are great “go to” folks!!

Jack
Outstanding
This is my second venture and second time with BayBiz and I wouldn’t have come back if their service wasn’t outstanding. I use them for their suite of services and David is always available if needed but Kerry and Mary do such a great job, I almost never need to bother the boss. Highly recommended if you want to spend more time doing business and less time on back office activities.

So happy!
